I was at a comedy club where the comedian was taking the piss out of gingers and scots. Being both, some of the crowd I was with looked round to see how I was taking this. Personally I was crying, I was laughing that much.

It is called humour - it's not personal and it's not banned...oh

Some people just need to learn how to laugh at themselves and other things around them. They may then stop being miserable bastards like dementors sucking the fun out of everyone else.
